Earlier quoted context omitted.
I wonder what a fair trial means to people...his own admissions include describing his own illegal activity...
You can admit guilt and plead innocent. It's weird, but it's true. And the jury can acquit in spite of overwhelming evidence of guilt. That's how the anglosaxon system of criminal justice works (or used to; perhaps this is only true now in the U.S.?).
It's not like a legal argument about what you knew or when and what the law says about your responsibility / actions.
A jury ignoring admissions of crimes is pretty rare and a roll of the dice.
I get why people would want that to happen, but expecting that random chance of an outcome and using it to measure fairness, I dunno, they're likely to be disappointed.
